(defmacro*-public markup (#:rest body)
"The `markup' macro provides a lilypond-like syntax for building markups.
- #:COMMAND is used instead of \\COMMAND
- #:line ( ... ) is used instead of \\line { ... }
- etc.
Example:
\\markup { foo
\\raise #0.2 \\hbracket \\bold bar
\\override #'(baseline-skip . 4)
\\bracket \\column { baz bazr bla }
}
<==>
(markup \"foo\"
#:raise 0.2 #:hbracket #:bold \"bar\"
#:override '(baseline-skip . 4)
#:bracket #:column (\"baz\" \"bazr\" \"bla\"))"
